      摘要： A tandem laser scanning unit (LSU) is provided. The tandem LSU includes a light source, a beam deflector, and an optical scanning lens. The beam deflector rotates on a light-emitting path of the light source to simultaneously deflect different light beams obliquely incident at a predetermined angle to each other within a sub-scanning plane substantially parallel to the rotational axis of the beam deflector. The optical scanning lens allows the light beams deflected by the beam deflector to be condensed on corresponding photosensitive drums. The optical scanning lens includes at least one sub-scanning cross-section having an aspherical surface to reduce the curvature of a scanning line. Using the tandem LSU, the distortion and curvature of the scanning line are corrected while providing an oblique incidence optical system having advantages in terms of manufacturing costs and driving efficiency.

        摘要： A light scanning unit includes a light source, a collimating unit for collimating light emitted from the light source, and a rotatory polygonal mirror for deflecting light radiated from the collimating unit. One sheet of an f-theta lens scans the light deflected by the rotatory polygonal mirror to a plane at a substantially uniform velocity to form an image on the plane and to correct a field curvature aberration in a main scanning direction. The f-theta lens may be a meniscus lens having a convex surface directed toward a deflection plane. A curvature of the f-theta lens in the main scanning direction differs from a curvature in a sub scanning direction. The f-theta lens has an aspherical shape in which a curvature in the sub scanning direction is varied continuously. A ratio of the radius of curvature of a first surface to the radius of curvature of a second surface at an optical axis is approximately at least 1.7.

        摘要： A laser scanning unit and an image forming apparatus having the same are provided. The laser scanning unit includes a plurality of light sources symmetrically disposed, and a rotatable deflector deflecting slantingly incident light beams symmetrically in a sub-scanning direction from the plurality of light sources. First and second f-θ lenses focus the light beams reflected by the deflector on scanning lines on photosensitive drums and are disposed symmetrically with respect to a rotational axis of the deflector. Mirrors guide the light beams that have passed through the first and second f-θ lenses toward the respective photosensitive drums. The mirrors are disposed asymmetrically with respect to the rotational axis of the deflector so that the scanning lines formed on the respective photosensitive drums may be deflected in the same direction.

        摘要： A scanning optical lens used for a laser scanning unit for imaging a laser, which is deflected by a beam deflection unit, on a photosensitive body. The scanning optical lens has a curvature of a Meniscus shape at a sub-scanning direction section, wherein the Meniscus shape has the same curvature symbols at an incidence surface and an exit surface at a center of the lens. The incidence surface and the exit surface always have negative (−) curvature symbols. An absolute curvature value of the incidence surface is maximal at the center, and has at least one minimal value at each of both sides in a main-scanning direction and wherein at least one of the minimal values is approximately zero.
